Title: Method for appraising activating degree in furnace core of blast furnace
Inventor: KIGUCHI MITSURU
IPC: C21B5/00
Filed: 1988-09-13
Abstract: PURPOSE:To appraise activating degree in furnace core of a blast furnace, to stabilize the blast furnace operation and to make low cost of the operation by measuring slag composition (Al2O3/CaO) in the furnace core of the blast furnace and comparing it with the average slag composition (Al2O3/CaO) charged into the blast furnace. CONSTITUTION:In the blast furnace operation, the slag in the furnace core part is sampled to measure the slag composition (Al2O3/CaO). This measured value is compared with the average slag composition (Al2O3) charged into the blast furnace to make an appraised index to the activating degree in the furnace in the furnace core. The condition of molten iron and slag flowing in the furnace core can be assumed from the difference between both and the activating degree in the furnace core can be quickly and directly informed at low cost. By this method, the blast furnace operation is stably controlled and the low cost operation can be executed.

Title: Solid-state image sensing device
Inventor: OSAWA SHINJI
IPC: H04N5/335
Filed: 1989-09-06
Abstract: PURPOSE:To increase maximum transfer electric charge of a vertical register to prevent reduction of accumulation capacity of a light receiving part by a method wherein a region having conductivity type opposite to that of the light receiving part is formed with a sufficient interval kept between the light receiving part and the vertical register. CONSTITUTION:Impurities of conductivity type opposite to that of a light receiving part 20 are implanted into a semiconductor substrate under a part of a gate electrode 22 to form an opposite conductivity type region 23. Thus p-n junction is formed between the region 23 and the light receiving part 20 so that reduction in accumulation capacity in the light receiving part 20 can be prevented. Since the region 23 is isolated from a vertical register 21 by a part 22' of the gate electrode 22, impurities do not reach the register 21 even if highly concentrated impurities are heat-diffused into the region 23. Therefore maximum transfer electric charge can be obtained in the register 21.

Filed: 1987-09-16
Abstract: PURPOSE:To lessen the amount of positional deviation of semiconductor pellets at the time of pickup of the semiconductor pellets by a method wherein an extensible sheet and a strong adhesive sheet are laminated to each other. CONSTITUTION:A semiconductor wafer is adhered on an extensible sheet 1 and after the wafer is formed into semiconductor pellets by dicing and cracking, this sheet 1 is extended to separate the pellets 2 from one another. After this, the sheet 1 is held on a cylindrical expansion ring 4 using a rubber 3, while a flat ring 5 with a strong adhesive sheet 6 adhered thereon is prepared and this ring 5 is fixed on a ring holder 7. Then, the ring 4 is placed and fixed on this holder 7 in such a way that the ring 4 is made to cover on this holder 7. Then, these sheets 1 and 6 are closely contacted to each other and are laminated to each other. Thereby, even in case the pellets 2 on the sheet 1 are picked up when a pellet attaching is performed, a change in the tension of the sheet 1 is not almost generated as there exists the sheet 6 and the positional deviation of the pellets 2 can be lessened.
